Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional swivel connection devices use multiple rings, central bodies, and screwable closing elements, then the connection can support rotational loads, but the assembly becomes complex and reliability decreases
Solution Approach 1:
The device is divided into three main functional segments: a housing body with connection seats, two coupling elements that can rotate relative to each other, and hinged connection means. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity and reliability.
Solution Approach 2:
The patent merges multiple functions into unified components. The housing body integrates connection seats and stop walls, the coupling elements combine rotational capability with load-bearing capacity, and the hinged connection means provide both structural support and rotational freedom. This merging eliminates the need for separate pins, screws, and multiple rings, reducing assembly complexity while maintaining reliability.
2Reliability
If traditional devices use pins, screws, and multiple load-bearing components, then the connection can be secured, but the manufacturing costs increase
Solution Approach 1:
The invention extracts and eliminates unnecessary load-bearing components such as pins, screws, and multiple closing elements from the traditional design. The coupling elements and hinged connection means are designed to provide both structural support and secure connection without requiring these additional fastening components, thereby reducing manufacturing costs while maintaining connection safety.
Solution Approach 2:
The design uses simpler, more cost-effective components that can be manufactured more easily. The coupling elements and connection seats are designed as single-piece or minimally assembled components that replace expensive multi-component assemblies, reducing overall manufacturing costs while maintaining adequate service life for the application.
3Adaptability or versatility
If traditional swivel connection devices use multiple rotatable rings and central bodies, then the device can handle rotational loads, but the assembly time increases
Solution Approach 1:
The coupling elements are pre-configured with rotational capability through the hinged connection means and connection seats. The stop walls are pre-positioned to guide the coupling elements into place, and the geometric connection is designed to automatically align components during assembly. This preliminary configuration eliminates the need for complex step-by-step assembly of multiple rings and central bodies, significantly reducing assembly time while preserving full rotational capability.
4Ease of operation
If traditional devices use complex geometric connections with multiple components, then the connection can be reversible, but the device complexity increases
Solution Approach 1:
Instead of using complex multi-component connections that require multiple steps to assemble and disassemble, the invention inverts the approach by designing a simple geometric connection where the coupling elements naturally engage with the connection seats through their shapes. The stop walls and geometric features provide automatic alignment and locking, making the connection both secure and easily reversible without complex mechanisms.
